前言
众所周知在spring boot内，设置session过期时间只需在application.properties内添加server.session.timeout配置即可。在整合shiro时发现，server.session.timeout设置为7200，但未到2小时就需要重新登录，后来发现是shiro的session已经过期了，shiro的session过期时间并不和server.session.timeout一致，目前是采用filter的方式来进行设置。

注册filter
在被@Configuration注解标注的类内注册ShiroSessionFilter。

@Value("${server.session.timeout}")private String serverSessionTimeout;@Beanpublic FilterRegistrationBean shiroSessionFilterRegistrationBean() { FilterRegistrationBean filterRegistrationBean = new FilterRegistrationBean(); filterRegistrationBean.setFilter(new ShiroSessionFilter()); filterRegistrationBean.setOrder(FilterRegistrationBean.LOWEST_PRECEDENCE); filterRegistrationBean.setEnabled(true); filterRegistrationBean.addUrlPatterns("/*"); Map<String, String> initParameters = Maps.newHashMap(); initParameters.put("serverSessionTimeout", serverSessionTimeout); initParameters.put("excludes", "/favicon.ico,/img/*,/js/*,/css/*"); filterRegistrationBean.setInitParameters(initParameters); return filterRegistrationBean;} |
这样当每次请求时，如果用户已登录，就重新设置shiro session有效期，从而和server session保持了一致。
